Not on U.S. iTunes for 2016

For my own reference when browsing eBay and the like, I used to keep a list of old albums and singles that had tracks not available on US iTunes. However, it wasn't really applicable to the modern day when everything was made available--at least until Tsunku stopped writing the majority of H!P songs and things stopped being so simple. So here is a list of what's easily missed from 2016. More or less in order of release.
